Seized & Jammed Lock Opening

The key slides all the way in, exactly as it has for years, and then refuses to turn in either direction. Yesterday it needed a small wiggle.

Seized & Jammed Lock Opening

In plain words

Most seized locks can be saved, and keeping your existing hardware is the aim. A cylinder that has stopped turning is usually recoverable with cleaning and fresh internal parts. A failed tailpiece is a small component swapped without touching the rest of the lock. A bolt bound by the door needs adjustment, not new hardware. Replacement is the answer for a plug or shell that is worn, damaged or hollowed out by corrosion beyond what cleaning and parts can fix, and then the new cylinder is matched to your keyway and finish and, where possible, keyed to the key already in your pocket.

Sound familiar?

The old mortise lock on the front door of the house turns the key halfway and stops with a dull clunk. It has been getting harder for months, and the brass key is starting to show a bend.

How the visit goes

Kitchener

How the visit goes

  1. What is inside the keyway

    A small mirror and a bright light show what the keyway has collected. Salt crust, sand, metal filings, sawdust from a renovation and the gummy residue of household spray oils are all common, and each reads differently: a dry gritty feel, a sticky drag, or a plug that will not accept the key to full depth. Ice shows as frost on the cylinder face and a key that stops short. A cylinder cap that has loosened lets the plug sit crooked so the pins never line up. This look decides whether the cylinder needs a flush and dry lubricant, a thaw, a re-tightened cap, or a full strip on the bench.

  2. Inside a mortise case or lever set

    For mortise locks and lever hardware the work moves from the cylinder to the case. The locksmith gets the door open, then removes the trim and draws the case out of the door edge. Inside, a broken lever return spring, a worn hub, a bent spindle or a latch that has lost its spring is replaced with the matching part, and years of dust and hardened grease are cleaned from the contact surfaces before a fresh application of a grease suited to lock mechanisms. The case is reassembled, the spindle and cylinder are refitted, and lever, key and thumb-turn are each tested so the latch and bolt travel fully.

  3. The early warnings to act on

    A lock gives notice before it seizes, and now you know the signs. A key that needs a jiggle to seat, a plug that turns stiffly on cold mornings, a bolt that drags in its pocket, a lever that returns slowly, or a key that comes out gritty are all invitations to act while the fix is small. Stop as soon as a key begins to bend; a snapped key turns a service call into an extraction. A puff of dry lubricant or a turn of the strike screws often settles it, and a call while the lock still turns is a shorter visit than a call after it stops.

What affects the quote

Same fees day, night or weekend

  1. 1Inside door or outside door

    A jammed bedroom or office privacy lock is generally a lighter job than a weather-exposed exterior deadbolt, and a mortise lock on an interior door sits between the two.

  2. 2Type of lock on the door

    A residential deadbolt, a knob latch, a lever set, a mortise case in an older house and a high-security cylinder each take different tools and time to open and to service.

  3. 3Door and hinge adjustment

    When the door caused the jam, hinge screws, shims, a strike move or a deepened bolt pocket are quoted as their own line beside the opening.

Seized & Jammed Lock Opening: questions

Will I need a whole new lock?

Usually not. Most jammed locks are saved by cleaning the cylinder, fitting a small part such as a tailpiece or spring, or adjusting the door so the bolt has room. A new cylinder is fitted when the plug or shell is corroded through or twisted by forcing, matched to your finish and, where possible, pinned to your current key. A complete new lockset is usually a choice you make rather than a requirement, though some internal failures cannot be serviced in place and call for a full replacement.

How long does a jammed lock opening take?

It depends on which family the jam belongs to. A bolt bound by the door is often freed in minutes and the adjustment afterwards takes a little longer. A seized cylinder needs patient cleaning before it turns and a bench service after, and a frozen one needs thawing time. A tailpiece swap is short once the door is open; a mortise case service is longer. The locksmith gives a sense of the time once the cause is identified at the door.

My key is worn. Would a new copy have prevented this?

Possibly, if the key was part of the cause. A worn or bent key lifts the pins short of the shear line, so the plug binds even in a healthy cylinder, and a copy made from that key repeats the wear. A key cut from the code or from a crisp original is the fix. If the lock was also gritty or the door had moved, the new key would have eased things without settling them, which is why the locksmith checks all three.
